Building Technical Standards
For judicial appraisals of pavements prior to the entry into force of the Technical Building Code CTE of 2006, we carried out, as a complement to the ENAC accredited test for Slip Resistance of Unpolished Pavements (USRV) according to Internal Procedure MF-01 Test method in situ, the test based on the standard NLT-175/73 of the Laboratory of Transportation and Soil Mechanics “Jose Luis Escario” according to the NTE-RSR: 1984 “Rigid pieces” (Technological Standards of the Building) which indicates that consider that:
“A pavement is non-slip when its coefficient of slip resistance measured with the Pendulum RRL (Road Researchy Laboratory) and according to the test standard NLT 175/73 of the Soil Transport and Logistics Laboratory-Jose Luis Escario- is greater than 40.”
Although the Technological Standards (NTE) are not mandatory, they become mandatory when they appear registered in the work project. It is very common to find projects executed between 1980-2000 in which the performance of the items is indicated in the measurement based on the Technological Standards, from that moment on, compliance with them is mandatory.
The difference with the Technical Code is that the technical code is always mandatory, whether or not it is indicated in the project, while the NTE must be fulfilled if compliance is specified in the work project.
