Saw and Seal - Involves making saw cuts in the overlaying asphalt, (above the joints) and sealing them with a compressible rubberized low modulus material 6 Economical option for controlling reflective cracking

Reflection Cracking – Pavement Interactive

Crack seal to prevent (1) entry of moisture into the subgrade through the cracks and (2) further raveling of the crack edges. In general, rigid pavement joints will eventually reflect through an HMA overlay without proper surface preparation.

Rubblization and crack/break-and-seat are effective techniques for reducing and possibly eliminating reflective crackling from old pavements. For overlays showing early signs of reflective cracking, the typical repair strategy to prolong pavement life is to perform crack sealing to prevent moisture from entering.

Slurry Seal - PPRA

CAPE SEAL (CHIP SEAL + SLURRY SEAL): For existing asphalt pavements with more extensive cracking than would be optimal for slurry seal alone, the chip seal application before slurry seal acts as a stress-absorbing interlayer more thoroughly sealing cracks and delaying the return of reflective cracking.

Reflective Cracking in Cement Stabilized Pavements

Cracking in asphalt pavements Cracks occur in flexible (asphalt) pavements for a wide variety of reasons. Some cracks are indicative of failure in the pavement, such as fatigue cracking, thermal cracking, or cracking due to base failure. Other cracks, such as reflective cracks in cement-sta-bilized pavement bases, are mainly cosmetic in nature ...

Chip Seal Treatment Types - Los Angeles County, California

A chip seal serves to seal the narrow cracks, help bind together cracked pavement, provide a wearing (driving) surface, and protect the underlying pavement structure. Chip seals used as interlayers serve to retard reflective cracking which develops from the bottom of the pavement structure towards the top.
