Almost all rigid pavement is made with Portland Cement Concrete (PCC). Rigid pavements are differentiated into three major categories by their means of crack control: Jointed plain concrete pavement (JPCP) This is the most common type of rigid pavement.
Maintenance – regularly timed pavement preservation treatments necessary for safety and to extend service life, typically for up to five years. Maintenance treatments can include crack sealing, seal coats, slurry seals, chip seals and overlays or any combination of these and other treatments.
Nam: PM= preventive maintenance; PCC = portland cement concrete. MOULTHROP AND HICKS. 5. Preservation Treatments. A number of preservation techniques for both flexible and rigid pavements are used worldwide.
Maintenance actions help slow the rate of deterioration by identifying and addressing specific pavement deficiencies that contribute to overall deterioration. Rehabilitation is the act of repairing portions of an existing pavement to reset the deterioration process.
Portland cement concrete (PCC) overlays are increasingly being used as a rehabilitation technique for both existing PCC and hot mix asphalt pavements by potentially extending service life, increasing structural capacity, reducing maintenance requirements, and lowering life cycle costs.
1 gru 2021 · For PCC pavement, the strategies are focused on “Slab Replacement – Corrective” for corrective maintenance; “Grind/Replace Slabs-CAPM”, ”Crack Seat and Overlay (CSOL)”, and “PCC Lane Replacement” for rehabilitation.
82-page summary of pavement preservation activities and recommended uses, expected longevity, and expected pavement life extension, with tools and techniques to help local agencies evaluate costs, benefits, timing, longevity, and decision-making for developing an effective pavement preservation program
