number of defects from occurring for example if the forwardly facing side surface 109 were to hit the base line 906 first the pavement marker 100 may flip upside down due to the combination of forces applied to the pavement marker 100 however too much tilt e g greater than 40 degrees may cause the pavement marker 100 to bounce leaving a divot in the base line 906 and may cause the pavement marker 100 to flip over the angle of the delivery chute 1024 may be selected based on the desired speed of the carrier 1000 for example the carrier 1000 may be moving at a speed of between 2 and 7 mph it has been observed that highway striping crews prefer to apply pavement markings at a speed of between 3 and 5 mph therefore the length and angle of the delivery chute 1024 and the corresponding rearward velocity may be fixed for the common case as depicted in fig1 alternatively as depicted in fig1 the angle of the delivery chute 1024 may be adjustable the delivery chute 1024 may have a slide portion 1103 connected to an upper portion 1106 by means of a hinge 1109 therefore the angle of descent may be varied by moving the slide portion 1103 in the direction of arrows 1112 or 1115 additionally the length of the delivery chute 1024 may be adjustable in some embodiments in various embodiments a change in the angle or length of the delivery chute 1024 may be partially or fully automated based on the speed of the carrier 1000 the delivery chute 1024 of fig1 exhibits a varied angle of descent by having a first slope 1203 and a second slope 1206 as shown the first slope 1203 has a steeper.
