Provided is a microtrench fill comprising concrete, a polymer, and a colorant. Also provided is a method of using the microtrench fill to fill a microtrench in a street or walkway.

Provided is a microtrench fill comprising cement, a polymer, and a colorant. Also provided is a method of using the microtrench fill to fill a microtrench in a roadway.

Provided is a microtrencher having a utility avoidance system that detects objects buried under the roadway, identifies whether the buried object is a utility and determines whether the buried utility is in the path of the cutting wheel. If the buried utility is in the path of the cutting wheel, an alert is sent to the operator, the vehicle is stopped, and/or the cutting wheel is raised in relation to the roadway. Also provided is a method of using the microtrencher to cut a microtrench in a roadway and to avoid cutting a buried utility in the path of the cutting wheel.

A device for sorting particulate material includes a main conveyor belt, a separation screen, a graded material conveyor, and an oversize material conveyor. The separation screen is configured to separate the material into a first portion and a second portion with a larger average particle diameter than the first portion. The graded material conveyor is positioned below the separation screen to receive the first portion of the material, and the oversize material conveyor is positioned at an end of the separation screen to receive the second portion of the material.

Hydro excavation vacuum apparatus that process spoil material onboard the apparatus by separating water from the cut earthen material are disclosed.

An apparatus for backfilling a trench and, more particularly, an apparatus for laying a pipeline bed layer in a trench and for laying a pipeline bedding layer once a pipeline is laid in the trench. The apparatus comprises a multi-deck screen vibrating unit. The upper deck screen comprises finger tines or a grizzly arrangement.

A mobile digging and backfill system for removing and collecting material above a buried utility. The system comprises a mobile chassis, a collection tank mounted to the chassis, a water pump mounted to the chassis for delivering a pressurized liquid flow against the material for loosening the material at a location, a vacuum pump connected to the collection tank so that an air stream created by the vacuum pump draws the material and the fluid from the location into the collection tank, and at least one backfill reservoir mounted to the chassis for carrying backfill for placement at the location.

A machine for backfilling pavement material into a trench defined within a pavement surface includes a frame defining a longitudinal axis and having at least one wheel. The frame being configured to move along the pavement surface. A hopper supported on the frame and including an inlet opening configured to receive pavement material and an outlet opening configured to discharge pavement material into the trench. The machine also includes a compactor supported on the frame and aligned with the hopper along the longitudinal axis. The compactor is configured to compact the discharged pavement material within the trench.
