A water-impermeable waterproof asphalt concrete composition having styrene isoprene styrene (SIS). The composition's waterproof performance due to its high cohesion and adhesion. The composition is durable and is not easily rutted, aged and/or stripped. In addition, the composition has a performance grade of PG 82-34, and can prevent water penetration and potholes. Furthermore, the asphalt concrete for prime coating and waterproof asphalt concrete can be applied to form an integrated structure by using a mixing/feeding system and can also be easily placed on site.

A nonvolatile cold modified asphalt binder and a nonvolatile cold recycled asphalt mixture using the same are manufactured by optimally mixing a petroleum asphalt, a native asphalt, a polymer modifier, process oil, and an adhesive strength enhancer. The nonvolatile cold modified asphalt binder includes at least one petroleum asphalt selected from a straight asphalt or a blown asphalt; at least one native asphalt selected from gilsonite, glance pitch, and grahamite; a rubber-modified-compound (RMC) polymer modifier which is a vinyl aromatic hydrocarbon-conjugated diene block copolymer including at least one of a styrene-butadiene block copolymer (SBS), a styrene-isoprene block copolymer (SIS), and a styrene-ethylene-butylene block copolymer (SEBS); at least one process oil selected from paraffin oil, naphthenic oil, aromatic oil, natural oil, and mineral oil; and at least one adhesive strength enhancer selected from rosin esters, modified acryls, modified silicones, polyvinyl esters, and silicone resins.

A system for spraying granular pasty matrices onto buildings. A spray gun for a wet mortar which makes possible the easy, safe and efficient spraying of wet mortars including aggregates with a particle size D50 of between 1 and 15 millimeters. The system which it concerns which includes spray gun for wet mortar provided with gun body, with at least one injector emerging in contacting chamber, at least one spray nozzle for mortar, and at least one connection end piece mounted on inlet of body for flow of mortar. Flow of mortar within the guiding duct of body is monodirectional or multidirectional (angular deviation<30°. The position of injection head of the injector in chamber is adjustable. The mortar is constituted by a pasty matrix including aggregates, fillers and additives. The aggregates have a D50=1-15 mm and a form factor F≠1.
