Analysis of bituminous crack sealants by physico-chemical methods and its relationship to field performance
Bituminous crack sealants were analyzed by viscometry, fluorescence microscopy, infrared spectroscopy, thermogravimetry, modulated differential scanning calorimetry and low temperature tensile testing. The results indicate that sealants are blends of bitumen, oil, copolymer and filler. Upon blending, these components produce a three phase system that consists of a polymer-modified bitumen (PMB)...
متن کاملPerformance of pavement crack sealants in cold urban conditions
Twelve bituminous hot-pour crack sealants were evaluated over four years in temperatures ranging from –40°C to +40°C. Each sealant was evaluated over 900 linear meters of transverse and longitudinal routs of 12 × 12 mm2, 19 × 19 mm2, and 40 × 10 mm2 (width × depth). Results show that sealant source, rout size, and rout orientation affected sealant performance, i.e., debonding and pull-out level...
متن کاملComparative evaluation of the microhardness of 4 dental sealants.
AIM Aim of this study was the evaluation of the microhardness of 4 dental sealants polymerised with two different curing units. METHODS Twenty samples (5 x 5x 2 mm) were prepared with 4 different sealants; 10 samples for each group were polymerised with a plasma curing unit (Apollo 95 E DMD) and 10 with a halogen curing light (Heliolux DLX Vivadent ETS, Schaan, Liechtenstein). For each sectio...

متن کاملBituminous Sealants for Pavement Joints and Cracks: Building the Basis for a Performance- Based Specification
Bituminous crack sealants are used to seal cracks and joints in pavements. In Canada and in regions experiencing harsh climates, sealants often fail prematurely, however. This is, in part, because it is difficult to select the best sealants, those that can withstand demanding conditions, based on the existing ASTM D3405 specification. Consequently, users would like to have a performance-based s...
