Transverse Cracking Study of Asphalt Pavement - Iowa

the amount of transverse cracking in asphalt pavements. Most of these have indicated that transverse cracking can be reduced through mix design procedures and asphalt grade and quality controls. There does not seem to be any follow-up reports which allude to any signi­ ficant success in the use of any of these procedures.

Asphalt Interlayer on Jointed Concrete - Iowa State University

After one winter season, 29 percent less reflective cracking was measured in the pavement with the interlayer than the pavement without the interlayer. The level of cracking severity was also reduced by using the interlayer. In the non-interlayer section, 41 percent of the total transverse crack lengths measured contained moderate severity cracks.
