ALCOLITE AL-280

ALCOLITE Raised Pavement Markers improve delineation and increase preview time, particularly under wet conditions. ALCOLITE raised pavement marker  provides a good reflective, painted, resilient, resistant, durable, sleek, innovative design that performs in weather resistant conditions, regardless of location.

 

 

Description

ALCOLITE  Raised Pavement Markers (RPM´s) have been designed to provide highly effective, long-term nighttime visibility in regions . The marker bodies are made of an engineering grade thermoplastic that provides high impact and weather resistance. The markers include retroreflective elements that provide wet retroreflectivity, dry retroreflectivity, long-term nighttime visibility and are available in white, yellow, red, blue or green.
ALCOLITE markers are designed to be compatible with commercially available epoxy and bitumen adhesives. The use of any other type of adhesive should be thoroughly evaluated prior to any large-scale application. The markers are designed for application on asphalt and Portland cement surfaces.

Markers are available in the colors

 Retroreflectivity

Retro reflectance refers to RPM´s luminance measured using simplified viewing conditions. Retroreflectivity is used for quality control purposes when specifying a single RPM´s type. RPM´s with white, yellow, red, green or blue reflective lenses have minimum initial retroreflectivity values as specified inTable , when measured according to ASTM test method. 
photometric quantity to be measured is the coefficient of retroreflected
The luminous intensity (Retroreflectivity Coefficient - RI), expressed in
millicandelas per lux (mcd/lx). 

Impact Resistance
According to the procedure mentioned in ASTM D4280, to verify the impact resistance of reflective lenses, a dart with a hemispherical head shall be impacted approximately at the center of the lens face. The lens shall be inspected for cracks and delamination.
The high impect pmma lens of the RPM's provides greater resistance for this test.
 

Abrasion Resistance
The coefficient of retroreflected luminous intensity of the Markers shall be measured after subjecting the entire lens surface to the test described in ASTM D4280, section using a sand drop apparatus. After the exposure described above, retroreflection values shall not be less than 0.5 times the values listed in Table. 

Temperature Resistance
Test RPM´s shall comply with the initial minimum brightness requirements specified in Table 3 and the product of the values in Tables 4 and 5 after being conditioned for 12 hours at 145 ± 5 °F (62.7 ± 2.5 °C).
3.7 Resistance to Water Penetration
RPM´s shall be conditioned for 10 minutes at 145 ± 5 °F (62.7 ± 2.5 °C) and then immediately submerged in a 70 ± 5 °F (21 ± 2.5 °C) water bath for 10 minutes. The Markers shall then be removed from the water bath and wiped dry with a soft cloth, visually inspected for water penetration behind the lenses, and measured for retroreflectance according to ASTM E809.
RPM´s shall meet the initial minimum retroreflectance values specified in Table 3.

Durability
Maximum RPM´s durability is achieved when RPM´s are properly applied according to all applicable recommendations provided in product bulletins. Because reflective performance is reduced by wear, the lens of the RPM´s is coated with an abrasion-resistant material which helps maintain retroreflective performance under normal traffic wear conditions. Minimal marker loss may occur under normal traffic conditions when applied according to recommendations using standard bitumen or epoxy adhesives designed for use with raised pavement
