The present invention relates to a polymerisable plasticiser formed by a hydrocarbon chain, one end of which bears more than one isocyanate function, said hydrocarbon chain comprising and/or being substituted by an aromatic ring and/or an aliphatic ring and/or said hydrocarbon chain is substituted by at least two hydrocarbon chains that can comprise an unsaturation, and the number of isocyanate functions being strictly greater than 1, preferably greater than 1.2, and, more preferably, grater than 1.5 but less than or equal to 2.2. The invention also relates to liquid polyurethane resin compositions and, in particular, stable, ready-to-use liquid polyurethane resin compositions comprising said plasticiser. The invention further relates to methods for replacing all or part of the exogenous plasticiser and/or solvent in a polyurethane resin by adding said polymerisable plasticiser.

This invention encompasses asphalt cement emulsions, as well as methods for preparing a pre-treated rubber-modified asphalt cement emulsions and methods for coating industrial surfaces using asphalt cement emulsions.

The present technology relates to ultra-low VOC compositions comprising asphalt, a softener, clay, a surfactant and one or more polymeric adhesives. The compositions may optionally include functional fibers, fillers and other additives. The present technology also includes methods of manufacturing and using such compositions in coating, sealing, waterproofing and other applications.

A device for manufacturing hot-mix coated materials includes an oven (1) having an enclosure (2) provided towards its two opposite ends with a main inlet (3) designed to receive granular materials and with a main outlet; and a heater (10) defining a combustion section (5) inside the enclosure (2). The enclosure (2) starting with the combustion section (5) and continuing with a drying section (6), and then with a mixing section (7). The device is further provided with a bypass outlet (11) and with an external mixer (12) that is connected to the bypass outlet (11), which outlet is fitted with a blocking system (15) allowing granular materials to pass towards the inlet (13) of the external mixer (12) and a closed position allowing granular materials to pass towards the mixing section (7).

A layered material includes a first carrier material and a second carrier material. The first carrier material is coated or saturated with a modified bitumen. The modified bitumen is a bitumen to which is added an agent selected from a wax, a silicone oil, stearic acid, alkene ketene dimer (AKD), alkenyl succinic anhydride (ASA), and mixtures thereof. The first carrier material is continuously attached to the second carrier material.

Plastomer-modified asphalt binders meeting MSCR specifications, asphalt paving materials with such asphalt binders, and methods for fabricating such asphalt binders are provided. The asphalt binder contains a base asphalt and a plastomer. If the plastomer has a drop point no greater than about 139° C., the asphalt binder further contains sulfur; sulfur-containing compounds, such as hydrocarbyl polysulfides and thiuram disulfides; phenolic resins; metal oxides; or a combination thereof. The asphalt binder is substantially free of elastomer.
