A structural layer laid on the old road surface to adjust the elevation, cross slope and flatness.
2.1.25 Permeable layer
A thin layer that penetrates the surface of the base layer by pouring emulsified asphalt, coal tar or liquid petroleum asphalt on the base layer to ensure good bonding between the asphalt surface layer and the non-asphalt base layer. 2.1.26 Adhesive layer
A thin layer of asphalt material spread to strengthen the bonding between the asphalt layers of the road surface and between the asphalt layer and the cement concrete pavement. 2.1.27 Seal layer
A thin layer of asphalt mixture laid to close the surface gaps and prevent moisture from invading the surface layer or base layer. The layer laid on the surface layer is called the upper seal layer, and the layer laid below the surface layer is called the lower seal layer.
2.1.28 Slurry seal
Use appropriately graded stone chips or sand, fillers (cement, lime, fly ash, stone powder, etc.) and emulsified asphalt, admixtures and water in a certain proportion to form a flowing asphalt mixture, which is evenly spread on the road surface to form an asphalt seal. 2.1.29 Wear layer
A thin structural layer paved on the top of the asphalt surface layer with hard fine aggregate and binder to improve driving conditions, prevent wear on the surface layer by driving, and extend the service life of the road surface. 2.1.30 Asphalt surface treatment pavement
Use asphalt and aggregate to lay or mix in layers, and the thickness of the thin surface layer is not more than 3cm.
2.1.31 Asphalt surface treatment pavement by layer laying method Asphalt surface treatment pavement is formed by pouring asphalt in layers, spreading aggregates, and rolling. 2.1.32 Single-layer asphalt surface treatment pavement: a layered asphalt surface treatment pavement with a thickness of 1 to 1.5 cm (0.5 cm for emulsified asphalt surface treatment) after pouring asphalt once and spreading aggregate once. 2.1.33 Double-layer surface treatment pavement
A layered asphalt surface treatment pavement with a thickness of 1.5 to 2.5 mm (1 cm for emulsified asphalt surface treatment) after pouring asphalt twice and spreading aggregate twice. 2.1.34 Three-layer surface treatment pavement
A layered asphalt surface treatment pavement with a thickness of 2.5 to 3 cm (3 cm for emulsified asphalt surface treatment) after pouring asphalt three times and spreading aggregate three times. 2.1.35 Asphalt penetration pavement
On the preliminarily compacted crushed stone (or crushed gravel), asphalt is poured in layers, caulking material is spread, or a hot mix asphalt mixture seal is laid on the top, and then compacted to form an asphalt surface layer.
2.1.36 Asphalt mixture
A general term for a mixture made by mixing mineral aggregate and asphalt binder. 2.1.37 Asphalt concrete mixture

Engineering construction standard full text information system
An asphalt mixture that meets technical standards and is made by mixing mineral aggregates that meet the specified grading and are composed of appropriate proportions of coarse aggregate, fine aggregate and filler with asphalt binder (represented by AC, and LH when a round hole screen is used). 2.1.38 Dense-graded asphalt concrete mixture: It is an asphalt mixture made of mineral aggregates with various particle sizes that are continuously graded and interlocked and compacted, mixed with asphalt binder, and with a residual void ratio of less than 10% after compaction. The residual void ratio is 3% to 6% (2% to 6% for pedestrian roads) for Type I dense asphalt concrete mixture, and the residual void ratio is 4% to 10% for Type I semi-dense asphalt concrete mixture.
2.1.39 Semi-open graded asphalt mixture
Mixed with appropriate proportions of coarse aggregate, fine aggregate and a small amount of filler (or no filler) and asphalt binder, the semi-open asphalt mixture with a residual void ratio of more than 10% after compaction is also called asphalt crushed stone mixture (expressed by AM, and LS when a round hole sieve is used).
2.1.40 Open graded asphalt mixture
The mineral aggregate gradation is mainly composed of coarse aggregate, with less fine aggregate, and the mineral aggregates are separated from each other. The void ratio after compaction is greater than 15%. 2.1.41 Discontinuous graded asphalt mixture
Asphalt mixture with discontinuous gradation formed by the lack of one or more grades in the mineral aggregate gradation composition.
2.1.42 Emulsified asphalt crushed stone mixture
Made by mixing emulsified asphalt and mineral materials at room temperature, the asphalt mixture at room temperature with a residual void ratio of more than 10% after compaction. 2.1.43 Sand-type asphalt mixture
Asphalt mixture with a maximum aggregate size equal to or less than 4.75mm (round hole sieve 5mm), also known as asphalt stone chips or asphalt sand. 2.1.44 Fine-grained asphalt mixture
Asphalt mixture with a maximum aggregate size of 9.5mm or 13.2mm (round hole sieve 10mm or 15mm).

Asphalt mixture with intermittent grading due to the lack of one or several grades in the mineral aggregate grading composition.
2.1.42 Emulsified asphalt gravel mixture
Asphalt mixture at room temperature, which is made by mixing emulsified asphalt and mineral aggregate at room temperature and has a residual void ratio of more than 10% after compaction. 2.1.43 Sand-type asphalt mixture
