Latex modified seal coat, cost effective long lasting asphalt surface preservation and beautification. Crack Sealing Sealing open cracks to provide a waterproof bond Slurry Seal Latex modified Type 1, 2 and 3 provides a new aggregate surface over aged and raveled asphalt surfaces.
Polymer-modified asphaltic waterproof coatings are bitumen-based fluid-applied coatings often for below-grade applications. Asphalt has very good water resistive properties, however, lacks strength at ambient temperature and flexibility at lower temperatures.
The chemical composition of asphalt had a significant effect on the properties of the SBS latex-modified asphalt. High asphaltenes and low resins were favorable to enhancing anti-rutting and recovery properties but weakened the anti-fatigue, compatibility, and storage stability of modified asphalt. Furthermore, compared to SBS particle …

The rheological properties (complex modulus and phase angle) at intermediate to high temperatures can also be measured using DSR. In this study, the controlled asphalt and modified asphalt with LDP, HDP, and CR (5%, 10%, and 15%) by weight of bitumen were tested using DSR following the standard conditions of the SuperPave binder tests [30].
It is found that when asphalt is modified with 0.6–4.5 wt% of NR, 1–2 wt% of PPA and 0.3–1.0 wt% sulphur (based on 100 parts of NR), penetration of the modified asphalt systematically decreases while its softening points …
