Abstract
A compactor includes a frame, an engine coupled to the frame, an exhaust system coupled to the engine and configured to remove heated exhaust air from the engine, a compacting member rotatably coupled to the frame and configured to rotate in contact with a substrate of paving material, and an air system. The air system couples the exhaust system to the compacting member.
Claims21
A compactor comprising:
- a frame;
- an engine coupled to the frame;
- an exhaust system coupled to the engine and configured to remove a heated exhaust air from the engine;
- a compacting member rotatably coupled to the frame and configured to rotate in contact with a substrate of paving material;
- and
- an air system comprising:
- a controller;
- and
- a mixing valve;
- wherein the air system couples the exhaust system to the compacting member and the heated exhaust air and an ambient air are proportionally introduced into the compacting member.

A compactor comprising:
- a frame;
- an engine coupled to the frame;
- an exhaust system coupled to the engine and configured to remove a heated exhaust air from the engine;
- a tire rotatably coupled to the frame and configured to rotate in contact with a substrate of paving material;
- an air system comprising a mixing valve and an air compressor, wherein the air system couples the exhaust system to the tire;
- a pressure sensor coupled to the tire and configured to measure the pressure of the tire;
- a temperature sensor coupled to the tire and configured to measure the temperature of the tire;
- and
- a controller that proportionally introduces the heated exhaust air and an ambient air into the tire, wherein the controller is configured to:
- receive the pressure of the tire from the pressure sensor;
- receive the temperature of the tire from the temperature sensor;
- actuate the mixing valve and the air compressor to adjust the pressure of the tire to a first pressure;
- and
- actuate the mixing valve and the air compressor to adjust the temperature of the tire to a first temperature.

A heating system for heating a compacting member of a compactor, comprising:
- an air system comprising a mixing valve for delivering a heated exhaust air and an ambient air into a compacting member;
- a temperature sensor for measuring a temperature of the compacting member;
- a pressure sensor for measuring a pressure of the compacting member;
- and
- a controller in communication with the temperature sensor, pressure sensor, and air system, wherein the control proportionally introduces the heated exhaust air and the ambient air into the compacting member and is configured to:
- control the pressure of the compacting member;
- and
- control the temperature of the compacting member.
