A milling machine may have a frame extending along a longitudinal axis and a milling drum attached to the frame. The milling machine may have ground engaging tracks that support the frame, and height-adjustable leg columns connecting the frame to the tracks. The milling machine may also have an engine for rotating the milling drum and propelling the ground engaging tracks. The milling machine may have a slope sensor to measure a roll angle of the frame, a speed sensor to measure a ground speed, and a configuration sensor to measure a machine configuration parameter. The milling machine may also have an alarm device and a controller. The controller may determine a threshold roll angle based on the machine configuration parameter, compare the roll angle with the threshold roll angle, and activate the alarm device when the roll angle is greater than or equal to the threshold roll angle.

Applicator and method for applying melted rubber to pavement comprises a melting vat having a substantially planar bottom with a surface area, and a wide-area a heating element beneath the melting vat having a surface area more than half the surface area of the planar bottom of the melting vat and positioned beneath the melting vat. The heating element may be comprised of an aluminum oxide ceramic blanket. A double-walled construction of the vat with exhaust holes in the outer wall allows exhaust to evenly melt rubber in the vat to reduce burning of the rubber, flame blowouts, and improve fuel efficiency.

A method for repairing/treating a pavement with the use of a rheology modifier is disclosed. The method comprises first applying a layer of a rheology modifier composition comprising a rejuvenating component onto the top surface of the pavement that needs repair, then applying a second layer of a binder onto the rheology modifier layer. The second layer of binder effectively seals the rheology modifier layer with the rejuvenating component for intimate contact with the top pavement surface, thus penetrating the surface layer to extend the life of the pavement surface, arresting the deterioration of visco-elastic properties and restoring some of those properties.

Disclosed is a chisel with double limit discs. The chisel includes a holding seat and a bit mounted on the holding seat, the bit including a head and an extension provided on the lower side of the head, a first limit disc and a second limit disc arranged up and down are mounted between the holding seat and the head, the middle of the first limit disc having a first mounting through hole, and the middle of the second limit disc having a second mounting through hole, the second limit disc being partially concaved or partially convexed with the first limit disc. For the chisel, the service life of the holding seat and the bit are prolonged, the coaxiality between the chisel position and the holding seat position is maximized guaranteed, and the chisel may maintain the optimal rotary cutting performance during operation.

The present disclosure describes systems and methods that employ a plurality of microwave applicator cells as a combined unit to continuously travel along an asphalt surface to treat the existing asphalt with microwave energy. The microwave treatment reanimates the existing (and likely damaged) asphalt to a workable state that is almost identical in nature to newly laid asphalt. The microwave system is configurable to span the width of a standard road lane, wherein the continuously traveling system efficiently repairs damaged roads with minimal down time.

According to examples, a method may include pouring a fluid ultra-high performance concrete (UHPC) mixture into a cavity, thereby providing a UHPC having at least one exposed surface. The method may include applying a liquid polymer onto the exposed surface of the UHPC, thereby providing a layer of liquid polymer onto the at least one exposed surface. According to examples, the method may include rolling the layer of the liquid polymer layer on the at least one exposed surface of the UHPC with a spike roller having a plurality of extended spikes. In some examples, the rolling may be applied with a predefined amount of pressure to cause the extended spikes to pierce the exposed surface of the UHPC, to incorporate the liquid polymer into the UHPC.
