Materials:
The trench system bodies shall be manufactured
from polyester polymer concrete with the minimum
properties as follows:
Compressive strength: 14,000 psi
Flexural strength: 4,000 psi
Water absorption 0.07%
Frost proof
Salt proof
Dilute acid and alkali resistant YES
Galvanized Steel Railings
The nominal clear opening shall be 4″ (100mm)with overall width of 5.12″ (130mm). Pre-cast units shall be manufactured with either an invert slope of 0.5% or with neutral invert and have a wall thickness of at least 0.50″ (13mm). Each unit will feature a partial radius in the trench bottom and a male to female interconnecting end profile. Units shall have horizontal cast in anchoring keys on the outside wall to ensure maximum mechanical bond to the surrounding bedding material and pavement surface. The galvanized steel edge rail will be integrally cast in by the manufacturer to ensure maximum homogeneity between polymer concrete body and edge rail. Each edge rail shall be at least 3/32″ (2.5mm) thick.
