Abstract

<B>"UTILIZAçãO DE UM SUBSTRATO ABSORVENTE DE SOM COMO UMA SUB-CAMADA EM UMA ESTRUTURA DE PAVIMENTAçãO"<D>. Um substrato absorvente de som (10) é utilizado como uma sub-camada em uma estrutura de pavimentação (1) que inclui um piso inferior (3) e um piso superior (5). O substrato (10) é feito de um material resiliente e, mais particularmente, de pneus reciclados. O referido substrato compreende uma superfície inferior (12) provida de cavidades (16) na forma de ranhuras que têm formado de U ou V e preferivelmente que se estendem em um ângulo de cerca de 45° com respeito a uma borda lateral do substrato. Essas cavidades deixam uma porção da superfície inferior em contato com o piso inferior. A relação de superfície inferior do substrato em contato com o piso inferior para a superfície desse piso inferior varia de 20 a 65%. Tal substrato (10) pode possuir espessura reduzida e ao mesmo tempo ainda possuir boas propriedades de absorção de som.
