Reflective Crack Relief Pavement Interlayer With Improved Load Bearing Capacity And Method For Designing Interlayer
US Patent:
7709106, May 4, 2010
Filed:
Jul 31, 2003
Appl. No.:
10/631149
Inventors:
Phillip B. Blankenship - Wichita KS, US
Richard Kent Steger - Wichita KS, US

Assignee:
Road Science, L.L.C. - Tulsa OK
International Classification:
B32B 9/00
US Classification:
428701, 428 95
Abstract:
A highly strain tolerant, substantially moisture impermeable, reflective crack relief interlayer is provided. The interlayer includes a polymer modified asphalt binder mixed with a dense fine aggregate mixture containing a substantial amount of manufactured sand. The interlayer mix is designed using a fatigue test and a stability test. Preferably, a hot mix asphalt overlay that is compatible with the interlayer, as well as the demands of local traffic and climate, is placed over the interlayer so that a protected, smooth paved surface is provided. The interlayer may delay the first appearance of cracks and the severity of cracks for several years compared with traditional hot mix overlays and extend pavement service life.

Assignee:
Shell Oil Company - Houston TX
International Classification:
C08L 95/00
US Classification:
106274, 106275
Abstract:
A method of making a sulfur-extended asphalt mixture with a minimum of hydrogen sulfide gas release into the atmosphere by using sulfur granules with specific physical properties and which are made by successively coating a starting sulfur seed particle with liquid sulfur that is solidified between coatings to thereby build up the a sulfur particle of a desired size. The sulfur granules are used to in the preparation of a sulfur, bitumen and aggregate mixture to provide the sulfur-extended asphalt.
