SynC · Topic
These are the standards in the SynC Standards library that cover Asphalt. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide — ratings, materials, setpoints, and the standards each is verified against. All of it is free to read without an account and published under CC BY-SA 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
Aggregate base course (ABC) for commercial, institutional, and industrial projects covering the placement, compaction, and quality control of crushed stone or processed graded aggregate used as the structural sub-base or base course beneath flexible (asphalt) and rigid (concrete) pavements, slabs-on-grade, building floor systems, exterior hardscape, equipment pads, and similar site improvements. Covers material classification and gradation, subgrade acceptance, geotextile separation where soft subgrades are encountered, lift placement, moisture conditioning, compaction, proof rolling, surface tolerances, and field testing. Intended to be read alongside the geotechnical investigation report, the civil grading drawings, and the structural or pavement section details, all of which govern design-specific values such as base thickness, target density, and material class.
Hot-mix asphalt (HMA) flexible pavement for commercial, institutional, and industrial site work, including parking lots, drive lanes, loading and service areas, fire lanes, and private site roadways. Covers surface (wearing) courses, intermediate (binder) courses, and asphalt base courses; prime and tack coats; performance-graded (PG) binder selection; Superpave and Marshall mix design and volumetric acceptance; reclaimed asphalt pavement (RAP) content; placement temperature and weather limits; lift thickness; in-place density and joint construction; and field testing for density, thickness, smoothness, asphalt content, and air voids. Intended to be read alongside the civil grading and paving drawings and the geotechnical report, which govern the design pavement section, course thicknesses, limits, grades, and drainage.
Seamless membranes built up in place from a liquid on concrete and masonry surfaces that enclose or protect occupied space: plaza and amenity decks, planters and landscaped areas, split-slab and topping-slab assemblies, between-slab and under-topping interior conditions, parking structure intermediate and roof levels with an exposed traffic-bearing membrane, and below-grade walls where a monolithic bonded membrane is selected instead of sheet. Covers hot fluid-applied rubberized asphalt and the cold liquid-applied chemistries (polyurethane, polymethyl methacrylate, polyurea, and polymer-modified asphalt emulsion), in both the buried configuration under a separate wearing course and the exposed configuration with an integral wearing surface, together with substrate preparation, primer, reinforcement, thickness control, protection course, drainage composite, root barrier, terminations, drains and penetrations, integrity testing, and warranty.
