摘要： A paving mat (14) for use in a paved surface (10) includes a fibrous mat in the form of a paving mat. The fibrous mat includes a fibrous matrix containing a mixture of polymer fibers, first mineral fibers having a first median length, and second mineral fibers having a second median length that is different from the first median length. In another embodiment, the paving mat includes a fibrous mat including a fibrous matrix which is bonded together by a binder. In one embodiment, the binder is a mixture of different binders. The fibrous matrix includes a mixture of mineral fibers in an amount within a range of from 61 wt% to 85 wt% and polymer fibers in an amount within a range of from 15 wt% to 39 wt%. The polymer fibers have a melting point greater than 320°F (160°C). The mat has a stiffness in the machine direction within a range of from 65 g-cm to HO g- cm. The mat has a load-elongation behavior such that when the mat is subject to tensile stress, the mat achieves at least 90% of its ultimate load at an elongation not greater than 5% of the specimen length in the direction of applied stress. Another embodiment of the paving mat is made with a carboxy-modified acrylic binder.

摘要： Fibrous insulation products have an aqueous binder composition that includes a carbohydrate and a crosslinking agent. In exemplary embodiments, the carbohydrate-based binder composition may also include a catalyst, a coupling agent, a process aid, a crosslinking density enhancer, an extender, a moisture resistant agent, a dedusting oil, a colorant, a corrosion inhibitor, a surfactant, a pH adjuster, and combinations thereof. The carbohydrate may be natural in origin and derived from renewable resources. Additionally, the carbohydrate polymer may have a dextrose equivalent (DE) number from 2 to 20. In at least one exemplary embodiment, the carbohydrate is a water-soluble polysaccharide such as dextrin or maltodextrin and the crosslinking agent is citric acid. Advantageously, the carbohydrates have a low viscosity and cure at moderate temperatures. The environmentally friendly, formaldehyde-free binder may be used in the formation of insulation materials and non-woven chopped strand mats. A method of making fibrous insulation products is also provided.
