Road Maintenance and Rehabilitation (M&R)

All information on this page is preliminary.

Pavement begins to degrade shortly after being applied to a roadbed. How much time passes before damage progresses and becomes visible is dependent on a number of  variables such as temperature, freeze-thaw cycles, vehicle weight, and usage frequency.

Maintenance

Maintenance actions, such as crack sealing, joint sealing, fog seals, and patching help slow the rate of deterioration by identifying and addressing specific pavement deficiencies that contribute to overall deterioration (go to source).

Rehabilitation

Rehabilitation is the act of repairing portions of an existing pavement to reset the deterioration process. For instance, removing and replacing the wearing course in a pavement provides new wearing course material on which the deterioration process begins anew. (go to source).

M&R Options

Transfer

Transfer responsibility for road maintenance and repair to Lewis County.  At some point in the past, this was assessed and will be documented on this site as information about it is received.

DIY

Community volunteers have been performing some maintenance activities such as trimming vegetation along the road and applying repair material to areas of road damage.

Contract

Any significant rehabilitation tasks would require a pavement contractor.

M&R Approach

What follows are steps in a draft process that could be used to maintain Tanglewood Drive. 

Develop M&R Categories and Costs

M&R of pavement has been accomplished for decades and guidance exists which can be used to describe pavement damage and repair costs.

Describe and Categorize Damage

Describing the damage condition of the road is required to develop approaches for M&R.  Ultimately the condition description enables the association of damage with M&R approaches, cost, and the development of an estimated service life.

Associate M&R Options with Specific Road Damage

Once damage has been categorized, the M&R options for the damage can be cataloged and assessed relative to a particular location. The options will range from least expensive to most expensive, and from least effective to most effective in extending the service life of the pavement. 

Develop Recommendations for M&R

For any given damage location, multiple M&R approaches could be applied. The primary trade-off will likely be cost versus service life extension whether the repair is accomplished using a pavement contractor or member labor and materials.

The development of the recommendations should also include a suggested prioritization of various M&R actions.
