Asphalt
These are the standards in SynC Standards 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, with the standards each is verified against. All of it is written and maintained by SynC, free to read without an account, and published under CC BY 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.
Standards
- Aggregate Base Course
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.
- Asphalt Paving
Dense-graded hot-mix asphalt flexible pavement for commercial, institutional, industrial, and multi-family site work, including parking lots, drive lanes, loading and service areas, fire lanes, and private site roadways, placed on an accepted aggregate base, a chemically stabilized layer, or a reclaimed base. Covers adoption of the state DOT specification by reference as an alternative to the project-written requirements, the design traffic level and the course thicknesses the pavement design hands to the paving contractor, aggregate quality, performance-graded binder, reclaimed asphalt pavement and shingles, Superpave and Marshall mixture design and the volumetric criteria, warm-mix asphalt, prime and tack coats, plant production and hauling, weather limits, placement, lift thickness, compaction, joints, edges, paving over a geosynthetic interlayer, full-depth patching and reconstruction of an existing asphalt pavement, the asphalt courses over a full-depth reclaimed base, and acceptance for density, thickness, smoothness, and mixture conformance. Read alongside the civil grading and paving drawings and the pavement design in the geotechnical report, which carry the pavement section, the course thicknesses, the binder grade, and the design traffic the datasheet fields of this standard defer to them.
- Fluid-Applied Waterproofing
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.
