Laterlite Expanded Clay used as a component in the mix design of bituminous conglomerates improves their technical characteristics. Specifically it can be used for:
sound-absorbent road surfaces: a variable percentage of expanded clay included in the mix, from 11% – 13% by weight, significantly increases the sound absorption (by 3 dB)
improves the transversal attrition coefficients and reduces wear on anti-skid road surfaces, including on drained anti-skid surfaces, as compared to the best basalts
