Maintenance and Surface Preparation Activities Prior to Pavement Preservation Treatments (2021)

Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

A-1   A P P E N D I X A Questionnaire The following definitions are related to terms used in this questionnaire. • Pavement maintenance: actions taken to slow the rate of pavement deterioration by correcting specific pavement defects. Examples include crack sealing and patching. In the context of pavement preservation, this questionnaire seeks information on maintenance activities undertaken to improve the performance of a preservation treatment and not applied as a band-aid or stopgap treatment. • Surface preparation: actions taken on an existing pavement surface to improve smoothness, geometrics, cross-slope, or bond, prior to the application of a subsequent edge-to-edge treatment. Examples include milling or micro-milling, diamond grinding, or rut filling. • Pavement preservation treatment (also referred to as preventive maintenance treatment): a product applied to an existing pavement to prevent, delay, or slow the progression of pavement distresses, and to correct or restore surface characteristics such as smoothness and friction, without adding structural capacity. Examples of pavement preservation treatments for flexible pavements include chip seals, microsurfacings, and thin (usually less than 1.5 inches thick) overlays, while examples for rigid pavements include diamond grinding and load-transfer restoration.

Questionnaire A-3   3. How is the decision made to perform maintenance prior to pavement preservation? (select all that apply) If more than one response applies, please use the space at the end of the question to provide additional detail. r It’s an agency policy decision (e.g., we always seal cracks one year before a chip seal is programmed) r Specific maintenance/surface preparation activities are linked to specific preservation treatments, such as in a treatment specification r The need is scoped as part of the treatment design (e.g., this decision is made on a project by project basis) following established guidelines r Maintenance needs are assessed and acted upon locally, prior to preservation treatment application r Maintenance actions and pavement preservation treatments are not linked r Other (please describe) Comments ______________________________________________________________________ ______________________________________________________________________ 4. If maintenance (as part of pavement preservation) is a policy decision, please describe the policy or provide that policy via one of the following methods: • Email to dpeshkin@appliedpavement.com • Provide link to files below. • Upload now: Comments ______________________________________________________________________ ______________________________________________________________________ 5. What is the timing of the maintenance/surface preparation activity in relation to the timing of the preservation construction? m There is no set timing; maintenance can occur at any time m Maintenance must be completed at least a specified amount of time ahead of preservation m Depends on treatment (please explain links between required maintenance/surface preparation and specific preservation treatments)____________________________ Comments ______________________________________________________________________ ______________________________________________________________________

A-4 Maintenance and Surface Preparation Activities Prior to Pavement Preservation Treatments Maintenance must be completed: m Less than 6 months in advance of preservation m Less than 1 year in advance of preservation m Between 1 and 2 years in advance of preservation m Other (please describe)______________________________________________ Comments ______________________________________________________________________ ______________________________________________________________________ 6. Where in the agency is the decision most often made to perform maintenance or surface preparation before preservation? (select all that apply) If more than one response applies, please use the space at the end of the question to provide additional detail. r Locally (e.g., District) – Do practices vary? r Central Office r Contractor r Consultant r Other (please explain) r Not applicable (please explain) Comments ______________________________________________________________________ ______________________________________________________________________ 7. Is there an amount of pre-preservation maintenance or surface preparation work that is too much, so that neither that work nor the subsequent preservation treatment would be successful or cost effective? (please explain) m Yes _______________________________________________________________ m No ________________________________________________________________ 8. How is maintenance or surface preparation prior to preservation paid for? (select all that apply) r Agency funds r Federal funds r Depends (please identify the factors that affect this) ________________________ r Other (please explain) ________________________________________________ Comments ______________________________________________________________________ ______________________________________________________________________

Questionnaire A-5   9. If maintenance or surface preparation before preservation is required, does it always occur? m Yes m No Please provide reason(s). (select all that apply) r Insufficient staffing r Lack of equipment r Lack of training r Inadequate budget r Other (please describe) Comments ______________________________________________________________________ ______________________________________________________________________ 10. How is maintenance or surface preparation accomplished when the preservation treatment is applied with in-house resources: m Also, with in-house resources m Not with in-house resources: They are performed under a separate contract (e.g., part of a larger crack sealing contract) m Not with in-house resources: They are performed as part of a specific preservation contract m Other (please explain) m Does not apply (please explain) Comments ______________________________________________________________________ ______________________________________________________________________ 11. How is maintenance or surface preparation accomplished when the preservation treatment is applied under contract: m With in-house resources m Under the same contract as preservation treatment m Under a contract separate from the preservation treatment contract m Other (please explain) m Does not apply (please explain) Comments ______________________________________________________________________ ______________________________________________________________________
