Carater\u00edsticas<\/h2>\n

Durabilidade:<\/strong> Os geot\u00eaxteis s\u00e3o feitos de materiais de alta qualidade, oferecendo uma forte durabilidade e um desempenho anti-envelhecimento, garantindo uma efic\u00e1cia a longo prazo.<\/p>\n

Facilidade de constru\u00e7\u00e3o:<\/strong> Os geot\u00eaxteis s\u00e3o altamente flex\u00edveis e adapt\u00e1veis, permitindo cortes e uni\u00f5es f\u00e1ceis para se adaptarem a v\u00e1rios terrenos complexos durante a constru\u00e7\u00e3o.<\/p>\n

Custo-efic\u00e1cia:<\/strong> Em compara\u00e7\u00e3o com os materiais imperme\u00e1veis tradicionais, os geot\u00eaxteis s\u00e3o mais acess\u00edveis, reduzindo significativamente o custo dos projectos rodovi\u00e1rios.<\/p>\n

Fun\u00e7\u00e3o<\/h2>\n

Refor\u00e7o:<\/strong> Na constru\u00e7\u00e3o de estradas e caminhos-de-ferro, os geot\u00eaxteis aumentam a resist\u00eancia \u00e0 tra\u00e7\u00e3o e a estabilidade do solo, evitando a deforma\u00e7\u00e3o ou o colapso sob cargas pesadas de ve\u00edculos ou comboios.<\/p>\n

Separa\u00e7\u00e3o:<\/strong> Os geot\u00eaxteis actuam como uma barreira entre camadas de solo com propriedades diferentes, impedindo a mistura e assegurando a integridade estrutural a longo prazo.<\/p>\n

Drenagem: <\/strong>Os geot\u00eaxteis facilitam a drenagem da \u00e1gua em subleitos rodovi\u00e1rios ou ferrovi\u00e1rios, evitando a acumula\u00e7\u00e3o de \u00e1gua que pode enfraquecer a estabilidade e a durabilidade.<\/p>\n
