A reinforced textile support, particularly for bituminous membranes, made of at least one layer of polyester non woven web and continuous high modulus reinforcement yarns longitudinally set with respect to said layer. The reinforcement yarns consist of cellulosic fiber multi-filaments of the Lyocell type. The assembly is bound by mechanical needling or water entangling, stabilized by means of thermal treatment at a temperature of 200-250&#xb0; C. and consolidated by means of a chemical binder.

A non-woven product containing organic and/or mineral particles has a volume density less than 1 and has at least two layers of synthetic fibers or filaments superposed in the Z direction perpendicular to the XY plane of the product, having undergone at least one needling operation, where the non-woven product integrates particulate feedstocks of mineral and/or organic particles distributed in a monomodal or multimodal manner in the product and at least partially coated or encapsulated by binding material that can point-connect the filaments or fibers to one another. At least one population or fraction of organic and/or mineral particles, has a size such that:3&#xd7;(&#x221a;{square root over ()}), preferably 5&#xd7;(&#x221a;{square root over ()})where SMf corresponds to the mean cross-section of the fibers or filaments that form the layers, and v represents the mean individual volume of the organic or mineral particles.
